Application filed August 15, 190.2. Serial No. 119,783. (No modelJ v To@ZZ whom, t may concern:

Be it known that we, RICHARD B. EMMONS, residing at Galena, county ofCherokee, State of Kansas, and NEWTON MILLER, residing at Joplin, inthecounty of Jasper and State of Missouri, citizens of the United States,have invented certain new and useful Improvements in Ore-Separatore; andwe do declare the following to be a full, clear, and eXactdescription ofthe invention, such as will-enable others skilled .in the art to whichit appertains to make and use the same, reference being had to theaccompanying d rawings, and to the figures of reference marked thereon,which form a part of this specication.

This invention relates to ore-separators and contemplates an improvedapparatus of the wet-process type adapted to effect in ahighlyexpeditious manner a complete separation from the gangue of thevaluable material re-A` gardless of the degree of ineness of the lat-`ter, the apparatus being especially designed to treat slimes and likemasses and to work tailings, which are the result of the treat-l ment ofmaterials by other methods or ma-V lowing detailed description of theconstrucf tion and operation and to the accompanying drawings,illustrating theiapparatus in its preferred form, it being understoodthat various changes may be made therein without departing from thespirit of the invention as defined by the claims.

In the drawings, Figure 1 is a vertical central sectional View of anore-separator embodying the invention. Fig. 2 is a horizontal sectionalview on line 2 2 of Fig. 1, certain of the parts being omitted. Fig. 3is an enlarged detail`Y plan view of a collar carrying thebrush-supporting arms. Fig. 4 is a crosssectional view of the collar.Fig. 5 is a detail view of a split ring carried by the collar.

Referring'to the drawings by numerals, 1 denotes a foundation upon whichis erected a preferably circular series of uprights 2 2, formingsupports for the outer ends of radially-disposed beams 3 3. The beams,which incline upwardly from their forward ends, form the support for asloping circular table 4extend radial arms 9 9.

4, andthe inner ends of the beams are joined to a central spider 5,having an opening in which is secured a tubular casing 6, forming theguide for a vertically-movable casing 7, having at its lower end aspider 8, from which Fixed to the outer Yends of the arms 9 is acasing-wall lO, circular in form and having the proper diameter tosecure close contact between it and the outer edge of the table 4, asuitable packing 11 being interposed for a purpose presently tobe'stated.

12`is'a shaft secured at its lower end centrally to the spider 8 andextending vertically through and considerably beyond the telescopingcasings 6 and 7. Supported on the top of the casing 6 is a rotatablecylinder 13, having a centraltubular stem 14, loosely receiving thevshaft 12 and carrying at its upper end a bevel-gear 15, which mesheswith a bevel-gear '16 on a power-shaft 17. The cylinder 13 iscontinuously rotated about the shaft 12 through power applied at theshaft 17, and between its lower end and the `casing 6 is a step-bearing18. The material with Water is supplied to the cylinder through afeed-spout 19 and falls onto the cylinder-bottom, in which are providedoutlets 2O 20. The material is fed in a finely-divided state, and tofurther reduce and agitate the particles and keep the outlets open thereare provided balls 21 21, which revolve over the correspondinglyformedcylinder-bottom, the positions of the balls during the rotation of thecylinder being maintained by stationary arms 22 22, eX- tending into thecylinder and mounted in the manner presently to be described. Inasmuchas the arms extend nearly to the bottom of the cylinder they also serveas stirrers for the material. Y The material leaving the cylinder by theoutlets falls onto a conical circular plate 23, carried by andconsequently rotated with the cylinder. From the plate 23 the material.falls onto a stationary circular dish 24, the outer edge 25 of which isup- IOO ner edge of the table closely and affording the support for thedish, to which it is secured inside of the line of openings 26.

Surrounding the cylinder is a collar 29, provided with vertical grooves30, engaging splines 31 on the cylinder, whereby the collar rotates withand is vertically adjustable on the cylinder. In an annular recessin thecollar is loosely fitted a split collar 32, from which are erected rods33 33. These rods form the supports for the arms 22 22, and their upperends are secured to a cross-head 34, which is keyed to the shaft 12. Thecrosshead, rods, arms 22, and split collar are incapable of rotation,and to minimize friction between the split collar and collar 29 aballbearing 35 is provided. Fixed to and extending radially from thecollar 29 are arms 36 36, to depending portions of which are securedbrushes 37 37, made,preferably,of woven fabric. The brushes rotate withthe cylinder 13 and normally contact with the table 4, and to enableworn brushes to be readily replaced by new brushes the arms are made ofdetachable telescoping sections.

The casing-wall 10 and brushes are adjusted vertically as the materialaccumulates on the table 4. The shaft 12 is screw-threaded at its upperend and engages a threaded opening in a worm gear-wheel 38, mounted torevolve on an upper supporting-beam 3S). The worm gear-Wheel is revolvedby a worm 40, keyed to a power-shaft 41.

In operation the material falling from the dish 24 onto the table isagitated by the rotating brushes 37, and the separation of the valuableparticles is accomplished at the higher side of the table, the ganguebeing carried over the outer edge of the table and is conveyed away byatrough 42. Then the feed of material has progressed to a certain extent,the shaft 41 is set in motion and the Vertical shaft 12 is, through thedescribed gearing, raised, carrying with it the brushes and the wall 10.The elevation of the wall (indicated by dotted lines) forms an annularreceptacle for the material, the valuable particles being retainedtherein and the gangue washing away over the top of the wall. Theelevation of the wall is very gradual and its movement is timedaccording to the feed of the material and the nature and consistency ofthe mass. The packing 11 between the wall and table edge preventsleakage at this point and renders the annular receptacle when formedpractically water-tight. The wa ll being guided by the telescopingcasings 6 7 has a uniform and regular movement, thus insuring a uniformheight throughoutat all times. The brushes following the movement of thewall are immersed in the material to the proper extent regardless ofthedepth of material, thereby securing uniformity in treatment. After asui'licientamount of material has been treated clean water is runthrough the apparatus to convey the separated particles to a suitablereceptacle, and this may be accomplished by means of the trough 42. Thewall 10 and brushes are gradually lowered as the washing takes place,this being accomplished by means of a hand-operated gear-wheel 43, whichmeshes with the wheel 38, the Worm 40 being unclutched during theoperation.

We claim as our invention- 1. In an ore-separator, the combination of acircular table, a revoluble cylinder centrally abovethe table receivingthe material and provided with an annular bottom havingdischarge-outlets, Walls on the cylinder-bottom, fixed arms extendinginto the cylinder and engaging the balls to prevent travel thereof, andmeans to direct the material from the outlets onto the table.

2. In an ore-separator,the combination of a circular table, avertically-movable shaft central of the table, a vertically-movablecircular wall at the outer table edge connected with the shaft, a guidefor the movement of the wall, a feed-cylinder rotatable about the shaft,and arranged to discharge the material onto the table, a collarrotatable with and vertically movable on the cylinder and brushes at thetable connected with the said collar.

3. In an ore-separator, the combination of a circular table, avertically-movable shaftcentral of the table said shaft having athreaded portion operatively connected with gearing for raising and forlowering the shaft, a vertically-movable circular wall at the outertable edge connected with the shaft, a rotatable feed-cylinder having acentral tubular portion loosely receiving the shaft and provided withoutlets in its bottom, means for directing the material onto the table,balls in the bottom of the cylinder, a collar rotatable with andvertically movable on the cylinder, brushes at the table carried by thecollar, and a stationary collar around the aforesaid collar and carryingarms engaging the balls to prevent travel thereof.
